I got the sonic 85. Very good condition for a good price at my local dealer. Good price, but without a decent fin.

I normally use Tectonics fins. Would the tectonics falcon f1 be a good choice for the sonic 85? Or would the goldwing be a better option... I already own a 28cm goldwing and a 28cm northshore slalom, also 32 cm drake slalom pro wich I do not like. So need a good 30 and 32 cms...
